XL6006
General Description
The XL6006 regulator is fixed frequency PWM Boost (step-up) LED constant current driver, capable of driving Series 1W/3W/5W LED units with excellent line and load regulation. The regulator is simple to use because it includes internal frequency compensation and a fixed-frequency oscillator so that it requires a minimum number of external components to work. The XL6006 could directly drive 16 Series 1W/3W LED units at VIN=24V . The PWM control circuit is able to adjust the duty ratio linearly from 0 to 90%. An enable function, an over current protection function is built inside. An internal compensation block is built in to minimize external component count.
Wide 5V to 32V Input Voltage Range Maximum Boost Output Up to 60V 0.22V FB adjustable LED drive current Directly drive 16 Series 1W/3W LED at VIN=24V Fixed 180KHz Switching Frequency Max. 5A Switching Current Capability Up to 94% efficiency Excellent line and load regulation EN PIN TTL shutdown capability Internal Optimize Power MOSFET Built in Soft-Start Function Built in Frequency Compensation Built in Thermal Shutdown Function Built in Current Limit Function Available in TO263-5L & TO220-5L package
